check fuel psi, it needs at least 50 psi to start. I had this problem, did you change filter
Did you scan the system will save you a shit ton of time diagnosing. Crank position sensor controls spark cam pos sensor controls injection timing. Why did you replace pump to start w ? Just getting some background
Just because coil has spark dont mean its getting to engine. Distributor caps are notorious for internal failures .
